How to check if a string starts with a substring from an array of substrings in PHP

Answer 1

function startsWithAny($string, $substrings) {
    foreach ($substrings as $substring) {
        // Check if the string starts with the current substring
        if (strpos($string, $substring) === 0) {
            return true;
        }
    }
    
    return false; // Return false if no substring matches
}

$string = "abcdefg";
$substrings = ["xy", "poq", "mnop", "abc", "rsuvw"];

if (startsWithAny($string, $substrings)) {
    echo "The string starts with a substring from the array.";
} else {
    echo "The string does not start with any substring from the array.";
}



/*
run:

The string starts with a substring from the array.

Answer 2

function startsWithAny($string, $substrings) {
    foreach ($substrings as $substring) {
        // Use str_starts_with to check if the string starts with the substring
        if (str_starts_with($string, $substring)) {
            return true;
        }
    }
    
    return false; // Return false if no substring matches
}

$string = "abcdefg";
$substrings = ["xy", "poq", "mnop", "abc", "rsuvw"];

if (startsWithAny($string, $substrings)) {
    echo "The string starts with a substring from the array.";
} else {
    echo "The string does not start with any substring from the array.";
}
